We think of NASA as a space agency, but NASA also has eyes on our planet. NASA and its science partners have a collection of Earth observing satellites, some that circle Earth every 90 minutes.

NASA's view of Earth from space provides a perspective that can't be gained from the ground. Satellites circle the entire globe, seeing both where people live and the remote parts of deserts, mountains, and the vast oceans that are difficult, if not impossible, to visit. All of this data is important for helping us better understand our home planet.

NASA Scientist Dr. Michelle Thaller is available on Friday, April 21 from 6:00a.m. – 9:00a.m. EST to chat with you on camera about new NASA science, and show your viewers some of the great Earth science research NASA is doing.
